AI Generated Solution

To solve the problem of how long it takes for a train to cross a bridge, we can follow these steps: ### Step 1: Convert the speed of the train from km/h to m/s The speed of the train is given as 72 km/h. To convert this to meters per second (m/s), we use the conversion factor: \[ 1 \text{ km/h} = \frac{5}{18} \text{ m/s} \] Thus, ...
